You definitely miscounting some numbers - property taxes are high in FL because there is no state income tax.Management companies charge a lot and don't do much for the money, every light bulb replacement costs you dearly.Unless you plan to move there and do your own PM, that's to going to be a good project

The second contractor did not charge me for his services, I had to deal with and pay the subcontractors directly, and there was one who did a poor job, mainly because he needed direction (and that's what a GC is for). 

I charge $200/week for the first 4 occupied beds in 3 of the above houses. 

What does that look like.Interest Rate, last if the seller is selling at face value, are you ok with the interest rate being paid and keep in mind you will probably be paying a servicer out of that monthly payment - my servicer charges $18.50 a payment.  

That isn't quite a large line of credit for rapid acquisitions, but on the conventional side, LOCs are usually in the $1mm+ range.

At most you have only 14k for down payment with a conventional loan.  

Hopefully you also charged a pet fee.

So at ~7 years of useful life that's about 70% of value... what happens if I charge them $200 for deodorizing and then decide to replace the floors?

If you charge a move in fee, what is the incentive for the tenant to leave the property in a good condition on move out?  

I have conventional built homes that I rent that have no mortgage, I could refinance these to get money for this.I could get a home equity loan.I could get a loan against these new properties but I have heard there is a higher interest rate and harder to get these loans (less people offer these loans for mobile hoames.I know there are a lot of things to consider and a lot of options.Your thoughts are appreciated., Joe
